Is there way to limit MKMapView maximum zoom level?

the question is - is there a way to limit maximum zoom level for MKMapView? Or is there a way to track when user zooms to the level where there's no map image available?

Solution

  • You could use the mapView:regionWillChangeAnimated: delegate method to listen for region change events, and if the region is wider than your maximum region, set it back to the max region with setRegion:animated: to indicate to your user that they can't zoom out that far. Here's the methods:

    - (void)mapView:(MKMapView *)mapView regionWillChangeAnimated:(BOOL)animated
- (void)setRegion:(MKCoordinateRegion)region animated:(BOOL)animated
